-SKRLETON STRUCTURE :FOR CONCRETE WALLS.

To all whom it may concern:

Be it known that I, HENRY ROOT, a citizen of thenl United States, residing in the city and county of San Franciscoand State of California, have invented certain new and useful Improvements in Skeleton Structures for Concrete 'Walls,of which the following is a specification.

My invention relates to thatclass of tirebarrier walls in which a rigid skeleton-struc ture is embedded in a non-inflammable material.

My invention consists in the no'vel rigid skeleton-st-ructure which I shall now fully describe, by reference tothe accompanying drawings in whiehy Flgure 1 1s a perspective View of the skeleton-structure, showing 1t 1n connection wlth form-panels in which the non-inflamm'ableI4 material, such as concrete, is molded to embed the structure, and make the completed wall. Fig. 2 is a view showing an I-beam cross-section, which is the preferred form for the main-members or studs of the skeleton-structure., and showing also, the spac-l ing-members or pieces secured to the faces of the main-members or studs. Fig. 3 is a similar view showing a channel-section as a form for the main-members or studs. Fig. l is a similar View of a Z-section for the same purpose. Fig. 5 is apperspective view showing the preferred form of the spacingmembers or pieces before theyv are bent to shape. Fig. .6 is a View showin one of said spacing-members or pieces after it is bent and ready for use. f v

1 are the main members or. studs of the skeleton-structure. They `are best formed of some rolled section of metal, the preferred section being an I-beam, as `shown in Fig. 2. They may, however, be made of :other rolled` sections, as, for example, the

channel-sectionv of Fig. 3, or the Z-section of Fig. 4. These studs are spaced or separated as shown in Fig. 1, and may be tem.

porarily held bottom, n i

3 are the spacing members or spacingby clamps 2 at the top and pieces. These are made of angle iron, and

may have any suitable contour. In their best forml they are V-shaped as shown in Fig. 6. In this shape they are prepared from blanks Vas shown in Fi .5., wlth holes 4 punched in, one of their'anges. These spacing-pieces are set with. thelr punched s pecication of Letters Patent.

- Hanges flat against the opposite exterior faces'or edges of the studs, l; and rivets 5, through their holes, hold-them to said main- `members. They are-fitted with their openbases upward, that is, in the direction from which the concrete is fed, so that the latter may enter betweentheir legs and fill them; and said spacing pieces are best made of a base-Width sufficient to let their. extremities overlap or project beyond the edges ofthe faces of the studs, as seen in Figs. 2, 3 and 4, so that said extremities, projecting into theconcrete, serve to .better bind it and avoid a weakened line along the edges of the studs. e

The unpunched flanges of the spacing'- ieces extend out-wardly at right angles rom the faces ofthe studs; and against the edges of sai'd flanges, the form-panels 6 are placed, thereby giving the necessary space to fill inwithconcrete. y

When the form-panels are removed, as

, seen in two instances in Fig. 1, the concrete 7 will have embedded the skeleton-structure,y leaving onlytthethin edges of the spacing "loV pieces, at -or near the surface. The anglesection of the spacing pieces affords both a firm, stable bearing against the studs, and .provides means for firmly securing them to said studs, both of which are of advantage in this work. The -V-shape of the spacingpieces is also of advantage in affording a I' bearing for the adjacent corners of four If desired a sheet 8 of non-conducting material, such as'asbestos, may be placed between the spacing-pieces and the faces of the studs. This, when used, will be of advanktagei'n separating said spacing pieces from the studs, with regard to heat conductivity.' As before stated, Ithe only portions of the skeleton structure which are not deeply embedded in the concrete are'thev edges of the spacing-pieces. Such heat as these maybe subjected to will not under ordinary-circumstances be conducted to any extent to the` studs, which form the .back-bone of the structure, but if it be likely to be w conducted, and for extra precaution, the asbestos sheets 8 may be used, as stated.

The spacing pieces not only provide the necessary space for llin vin the concrete but also provide for embe dang 1n said concrete the horizontal reinforcement 'rods 9,

IFig. 1, which are wired to the' faces of the studs; and in such position are thus embedded deeply in the concrete. v

The whole skeleton-structure is deeply and uniformly embedded in the concrete; it does not spring under the ramming of the con- 'crete from each side; remains rigid in the and means for securing the s acing pieces at intervalsv to the exterior anges of the studs through said angled flanges, the V- shaped walls projecting outwardly fromv said flanges. 2. A skeleton-structure for concrete walls comprising studs; and metallic spacingpieces bent' to a V-shape and having an angled extension secured at intervals throuvh said extension to the exterior faces of tIie studs, the ends of said spacin `pieces extending beyond the edges of sai faces.
